Built from the same circuit platform as the PT12/20/30 controller the Feather Touch Zoom is controlled from eight 100 MHZ microprocessors in chip, doing over 100,000,000 instructions/second. Ramping, motor feedback controls, as well as rocker angle filtering are all done simultaneously at lightning speed.
This is what creates the smooth slowmovement of the Feather Touch Zoom while still having the capability of extremely fast movement. If your video zoom lens starts and stops when trying to go very slow, the Feather Touch will drive it better than a high quality Broadcast lens module. And the slip clutch means you don't have to know where the end stops are as the clutch releases as soon as it hits the stops for a seamless end.
